Smart factory as an important practice model of intelligent industrial development, has caused widespread concern in the industry. In the end what is smart factory? The core architecture of intelligent factory is like? Which can provide support for the restructuring of enterprises? This is a topic businesses are more concerned about.
intelligent factories, chemical plants and digital intelligent manufacturing can not be ignored is that many companies often when referring to these concepts, these concepts easily confused, in the end it can be replaced with each other between the digital factory, smart and intelligent manufacturing factories, these concepts whether there is a difference between? 1, the digital factory for the digital factory, the definition of the Association of Engineers in Germany are: Digital Factory (DF) is a comprehensive network of digital models, methods and tools Control Engineering Copyright including simulation and 3D / Virtual reality visualization, integrated by a continuous uninterrupted data management. Digital Factory integrates product, process and plant model database, through advanced visualization, simulation and document management, to improve product quality and production processes involved in quality and dynamic performance:
in the country, for the digital factory highest acceptance is defined as: digital factory is in a virtual computer environment, the entire production process simulation, evaluation and optimization, and further extended to the new production organization of the entire product life cycle. Modern digital manufacturing technology and computer simulation technology combined with the product, primarily as a communication bridge between product design and product manufacturing. From the definition can draw a conclusion, the nature of the digital factory is to achieve the integration of information. 2, intelligent plant factory is based intelligent digital factory based on the use of networking technology and monitoring technology to enhance information management services to improve the controllability of the production process, reducing manual intervention production line, as well as a reasonable planning and scheduling. Meanwhile, a preliminary set of emerging technologies such as intelligent tools and intelligent systems integration, building efficiency, energy saving, green, environmental protection, comfortable humanity chemical plant.
intelligent plant already has autonomy, acquisition, analysis, determination, planning; overall predicted by visual reasoning techniques, using simulation and multimedia technology, the amplification reality display design and manufacturing process. Each system may form part of their own optimal system configuration, includes the coordination, recombinant and expansion characteristics. The system already has a self-learning, self-maintenance capabilities. Therefore, intelligent plant to achieve mutual coordination and cooperation between man and machineIts essence is human-computer interaction. 3, intelligent manufacturing plant is an upgraded version of the intelligent digital factory basis, but there is a big gap and intelligent manufacturing. Intelligent Manufacturing Systems in the manufacturing process can be carried out intelligence activities, such as analysis, reasoning, judgment, and decision-making ideas. By working man and intelligent machines, to expand, extend and partially replace the mental technical experts in the manufacturing process. It extended to flexible manufacturing automation, intelligent and highly integrated.
Intelligent Manufacturing Systems not just “artificial intelligence system, but intelligent man-machine integration system is a hybrid intelligent system can undertake independent analysis, judgment, decision-making tasks, highlighting the centrality of man in the manufacturing system, at the same time intelligent machines with better play of human potential. machine intelligence and human intelligence truly integrate, complement each other, complement each other. essentially man-machine integration.
many domestic companies are intelligent manufacturing speculation, but never most enterprises are still in the stage part of the application software, only a small number of companies realize information integration, that is, you can reach the level of digital factory; very few companies able to achieve effective human-computer interaction, that is, to reach the level of intelligent factory Into Sany No. 18 factory No. 18 thirty-one plant is Asia’s largest intelligent manufacturing workshop, concrete machinery, road machinery, port machinery and other assembly lines, Sany assembly plant in 2008 began to build, 2012 in full production, with a total area of around 100,000 square meters. The total loading Sany Divided between the assembly area, high-precision machining area, structure area, Li reservoir, showing the six functional areas hall, landscape area; the main production truck, trailer pump, car pump motor graders, rollers, pavers, stackers and other products. factory comprehensive application of digital factory simulation technology planning program design and verification, a move that greatly enhanced the scientific planning and layout of rationality. 1, intelligent processing center and production line in Shanghai Lingang industrial Sany Park built the world’s largest and most advanced excavator production base CONTROL ENGINEERING China Copyright , a large-scale welding robots in use, making life thirty-one excavator about quadrupled sales, after sales fell by a quarter ter. At present, Sany has completed R & D workshop machines and equipment procurement and installation. 2, intelligent warehouse and logistics systemThirty-one intelligent warehouse by the Trinity United HUST research and, with a total investment of 60 million yuan, north and south two libraries, automatically fed by underground equipment together into a whole, a total area of 9,000 square meters, warehouse capacity is about 16000 cargo space. The reservoir area has thousands of materials to support the production of thousands of products per month. 3, intelligent control of the production process execution Trinity Group manufacturing execution systems, which make full use of information technology, issued from production planning, materials distribution, tact, to confirm the completion of the standard work instructions, quality management, and other vital pieces of barcode collection and more a control dimensions, and will promptly and accurately communicated to production managers and decision makers across the network in real-time on-site information. After 4, intelligent production control center used Andon system, if a problem occurs, the operator can pull the rope at the workstation or click the button to trigger the appropriate sound and light the corresponding indicator, suggesting that supervisors immediately find fault place and cause of failure, downtime can be reduced while improving productivity. Intelligent plant gene intelligent smart factory, people, machines and resources as naturally communicate with each other in a social network in collaboration, produced by the intelligence products to understand the details of how they have been produced and will be used, be able to answer “Which group parameter is used to handle me, “” I should be transferred to where to “and so on. Meanwhile, intelligent assistance system will perform routine tasks freed, allowing them to focus on innovation; flexible work organization can help workers to live and work to achieve better integration of individual customer needs will be met. 1, three yuan of industrial development strategy core strategy of the United States and Germany are CPS (Cyber- Physical System) system, it is a typical dual strategy. The United States is C (Cyber, including: digital, information, networking and other virtual worlds) + P (Physical, including machinery, equipment, facilities and other entities in the world), Germany P + C, the two countries are based on high-quality workers, the state lack of manpower, strategic business synergy high, high legalization basis proposed!
while Chinese equipment level than the United States and Germany have a certain gap, data acquisition and analysis decision-making ability has limitations, but China has advantages in human resources, so it should fully tap the role of people. Therefore, Chinese manufacturing enterprises to promote industrial development can not copy the developed countriesDual strategy, but it should adopt the CPPS (Cyber-Person-Physical System) strategic human network three yuan, fully reflects the active role of people. 2 six-dimensional smart-called “six-dimensional intelligence theory”, that is the basis of networking equipment + remote data collection on the Control Engineering Copyright , production process management and intelligent control, build from six aspects China’s national conditions of intelligent plant, which includes six aspects:
intelligent planning schedule, is an integrated ERP program from the source, a senior APS scheduling. Smart co-production, from the production preparation process, to achieve simultaneous material, cutting tools, tooling, process of collaborative preparation. Intelligent equipment interoperability, is a typical manifestation of physical CPS information systems, digital production equipment distributed network communications, program management centralized, real-time monitoring of equipment status and so on. Intelligent resource management, including materials, equipment, tools, measuring tools, fixtures and other production resources lean management, inventory intelligent early warning. Intelligent quality control process is the production process parameters affecting product quality, real-time acquisition and control, to ensure product quality. Intelligent decision support, decision support based big data analytics, form a closed loop management to digital, networked, intelligent and efficient mode of production. What intelligent factory industry 4.0 is the core architecture? Everyone will have different viewpoints different understanding is interconnected, integrated (vertical, horizontal, end to end), data, innovation, service, restructuring or CPS, smart factory is also manufacturing intelligence or national strategy ,Enterprise’s goal. Industry 4.0 core content is to build a network of three integrated, big data analytics, and research plans eight two themes. 1, to build a network (CPS) CPS allows physical devices with computing, communications, precise control, remote and autonomous coordination five functions , in order to achieve integration of the virtual online world with the real physical world the advanced computing power of cyberspace effectively used in the real world, so that in the manufacturing process, and the design, development, production of all relevant data will be collected and analyzed by sensors to create intelligent production systems can operate self-discipline. 2, three of three integrated industrial integration 4.0 comprising: a horizontal integration, integrated with the integrated longitudinal end to end.
